Fungi account for what percentage of plant diseases?

• A. 90%
• B. 60%
• C. 80%
• D. 70%

Answer: (C)

Fungi are the dominant cause of plant diseases, responsible for roughly four-fifths of recorded plant diseases. Their vast diversity includes rusts, mildews, blights, rots, and many other diseases, and their spores spread easily in a wide range of conditions, allowing infections across many crops, ornamentals, and trees. This combination of widespread hosts and efficient transmission means fungi represent the large majority of plant disease problems, which is why about 80% is the standard estimate. Some sources note higher figures in certain contexts, but 80% is the commonly accepted value. Percentages like 90%, 70%, or 60% are less consistent with the overall pattern seen in plant pathology.
